Standard Series:

Product Material Composition:

• Filament Material: Silicon carbide (SiC) abrasive nylon filament – nylon bristles with very high silicon carbide grit content for general-purpose use. Abrasive grains are embedded in flexible plastic filaments, which means the filament works on the sides as well as at the tip.

• Shank / Base Material: Steel shank with solidly cast-in-place construction – 6mm or 8mm straight shank for direct mounting in drill presses, machining centers, and power tools. Disc brushes with extremely tightly packed abrasive bristles (right to the edge of the brush) embedded in the plastic pad.

Product Features and Applications:

Our Shank-Mounted Silicon Carbide Abrasive Filament Disc Brush features a straight shank design that allows direct chuck mounting in drill presses, machining centers, and power tools. The disc brush is constructed with extremely tightly packed abrasive bristles (right to the edge of the brush) embedded in a plastic pad. The bristles support each other, giving a highly stable shape and very long working life. Nylon bristles with very high silicon carbide grit content make this brush suitable for general-purpose use.

Core Advantages:

• Straight Shank Design – 6mm or 8mm shank allows direct mounting in drill chucks, machining centers, and power tools for quick and secure installation

• Solidly Cast-in-Place Construction – integrated one-piece design with high concentricity and radial runout precision

• High-Density Filament Packing – tightly packed abrasive bristles right to the edge of the brush for maximum working area

• Shape Stability – bristles support each other, providing high stability and accuracy for process reliability

• Reproducible Results – continuous exposure of abrasive grit ensures consistent performance throughout the brush's life

• Long Service Life – extremely durable construction with very long working life

• Versatile Abrasive Action – abrasive grains embedded in flexible plastic filaments work on both sides and tips of the brush

• Post-Processing Directly After Machining – workpieces can be processed immediately after the machining operation

Application Fields:

CNC and Automated Machining:

• CNC machining centres and robotic applications

• Wet grinding with cooling lubricant is preferred for optimal performance

• Machining of flat components: precise deburring, edge rounding, finish machining after milling

Metal Processing:

• Aluminum die-castings, zinc alloys, and cast iron parts – end face and stepped hole deburring, flash removal

• Steel and stainless steel – rust removal, scale stripping, and surface preparation

• Automotive parts – cylinder heads, valve bodies, compressor housings – sharp edge removal and surface conditioning

• Hardware stampings – oxide layer removal and machining mark elimination on flat surfaces

Surface Finishing:

• Removal of fine milling cutter marks and vibration marks

• Surface finishing of sealing and mating faces

• Polishing and surface refinement after machining

Additional Applications:

• Die-casting industry – gate marks and parting line burr removal

• Composite materials – carbon fiber and fiberglass edge finishing

• Aluminum, brass, copper, and magnesium alloys – suitable for non-ferrous metals

Performance Comparison:

Material Compatibility:

• Aluminum-magnesium alloys – suitable

• Copper-zinc alloys (brass) – suitable

• Steel tensile strength < 900 N/mm² – suitable

• Steel hardness < 55 HRC – conditionally suitable

• Gray cast iron – conditionally suitable

• Titanium alloys – conditionally suitable

Application Limitations:

• Maximum working temperature: 80°C

• Dry operation: conditionally suitable

• Wet operation with cooling lubricant: preferred and suitable

Frequently Asked Questions (FAQ)

Q1: What is the advantage of the shank-mounted design?
The straight shank (6mm or 8mm) allows direct chuck mounting in drill presses, CNC machining centers, and power tools. This provides quick and secure installation without additional adapters, high concentricity, and reliable process safety.

Q2: Why choose silicon carbide (SiC) abrasive over other abrasives?
Silicon carbide provides high hardness and sharp cutting edges, delivering aggressive cutting power for heavy deburring, rust removal, and oxide scale elimination. SiC is the preferred choice for ferrous metals, castings, and applications requiring maximum material removal.

Q3: Is this brush suitable for automated CNC and robotic applications?
Yes. This brush is specifically designed for CNC machining centres and robotic applications. Wet grinding with cooling lubricant is recommended for optimal performance and tool life.

Q4: What is the recommended operating speed for this brush?
Recommended speed is typically 1,500–2,800 min⁻¹, with maximum speed up to 4,500 min⁻¹. Feed rate should be 800–3,000 mm/min with infeed of 0.3mm (fine) to 2.0mm (coarse).

Q5: Can this brush be used on aluminum or soft metals?
Yes. Silicon carbide disc brushes are suitable for aluminum-magnesium alloys and copper-zinc alloys. The flexible abrasive filaments provide controlled cutting that follows contoured surfaces without gouging. For soft metals, use lighter pressure to avoid over-cutting.
